Everything is good but the colour you used that is painful for eyes. So need to use white background that will better for everyone.

Thank you Subhasish for this very useful video ,but the piece of code for handling multiple windows in selenium(Qs. 11) is not very clear. Can you please paste the code in comment section .It will really be helpful for me.

[@SoftwareTestingAndAutomation]

Please find below piece of code.
public class MultipleWindowsClass {
@Test
public void testMultipleWindows() throws InterruptedException{
System.setProperty("webdriver.gecko.driver", System.getProperty("user.dir")+"\\src\\test\\java\\drivers\\geckodriver.exe");
// To open browser
WebDriver driver=new FirefoxDriver();
// To maximize browser
driver.manage().window().maximize();
// To open Naukri website with multiple windows
driver.get("www.naukri.com/");
// It will return the parent window name as a String
String mainWindow=driver.getWindowHandle();
// It returns no. of windows opened by WebDriver and will return Set of Strings
Set set =driver.getWindowHandles();
// Using Iterator to iterate with in windows
Iterator itr= set.iterator();
while(itr.hasNext()){
String childWindow=itr.next();
// Compare whether the main windows is not equal to child window. If not equal, we will close.
if(!mainWindow.equals(childWindow)){
driver.switchTo().window(childWindow);
System.out.println(driver.switchTo().window(childWindow).getTitle());
driver.close();
}
}
// This is to switch to the main window
driver.switchTo().window(mainWindow);
}
}
